The document discusses the historical context of industrial relations in the UK from the late 18th century to present day. It covers the development of trade unions and employers' organizations, as well as employment law and institutions. Trade unions first emerged in response to the industrialization and formation of a working class in the late 18th century. Over the 19th century, unions grew in size and legal recognition, while employers also organized themselves. Government policy shifted from hostility to support for collective bargaining between 1900-1970s. Conservative governments under Thatcher in the 1980s-90s significantly reformed employment laws weakening unions and shifting to local bargaining.
